Description
Technical field
This technology is related to telecommunication, and relates in particular to the uplink transmission of biconnectivity mode.
Background technique
In typical cellular radio system, wireless terminal (also referred to as mobile station and/or user equipment (UE)) via
Radio access network (RAN) is communicated with one or more core networks.Radio access network covering is divided into cell area
Geographic area, wherein each cell area can be referred to as such as " NodeB " (usually mobile electricity by base station, for example in some networks again
Letter system (UMTS)) or the radio base station (RBS) of " eNodeB " (long term evolution (LTE)) service is provided.Cell is a kind of
Geographic area, wherein providing radio covering by the wireless base station unit at base station site.Each cell passes through local wireless
Identification code in electric region identifies that the identification code is broadcasted by RBS in the cell.Base station connecing in the air in radio frequency by work
Mouth is communicated with the UE within base station range.
In some versions of radio access network, several base stations usually (such as passing through landline or microwave) is connected to control
Device node (such as radio network controller (RNC) or base station controller (BSC)) processed, controller node monitoring and coordinate and its
The various activities of multiple base stations of connection.Radio network controller is typically connected to one or more core networks.
UMTS is the 3-G (Generation Three mobile communication system) from the second generation (2G) global system for mobile communications (GSM) evolution.It is general
Terrestrial Radio Access Network (UTRAN) is substantially the radio access network that wideband code division multiple access is used for subscriber separation.Claiming
In the forum for making third generation cooperative partner program (3GPP), telecommunications provider specifically proposes and decides through consultation third generation networks and UTRAN
Standard, and study enhancing data rate and radio capability.3GPP has worked out the specification of evolution UTRAN (E-UTRAN).E-
UTRAN includes LTE and System Architecture Evolution (SAE).LTE is the variant of 3GPP radio access technologies, wherein radio base station
Node (via access gateway, that is, AGW) is connected to core network without being attached to RNC.In general, in LTE, RNC node
Function be distributed between radio base station node (eNodeB in LTE) and AGW.Therefore, the radio access network of LTE system
(RAN) there is substantially " flat " framework including radio base station node, without reporting to RNC node.
LTE uses orthogonal frequency division multiplexing (OFDM) in downlink and uses Discrete Fourier Transform in uplink
(DFT) OFDM is extended.Fig. 1 shows basic LTE downlink physical resource according to time frequency grid, wherein each resource element corresponds to
The OFDM subcarrier of one OFDM symbol interim.It in the time domain, is 10 ms' by LTE downlink transmission tissue
Radio frame, each radio frame is by length TsubframeThe subframe of ten equal sizes of=1 ms forms, as shown in Figure 2.
Resource allocation in LTE is described generally according to resource block (RB), and wherein resource block corresponds to one in time domain
12 contiguous subcarriers in time slot (0.5 ms) and frequency domain.Two Adjacent resource blocks of a pair of time orientation (1.0 ms) claim
Make resource block pair.Resource block is numbered in a frequency domain, since one end of system bandwidth is by 0.
In a frequency domain, LTE downlink uses 15 KHz subcarrier spacing.Therefore, resource block corresponds to one in time domain
12 contiguous subcarriers in a time slot (0.5 ms) and frequency domain.The secondary load that resource element (RE) is then defined as in frequency domain
The duration of an OFDM symbol in wave and time domain.
Physical layer channel in LTE uplink is believed by Physical Random Access Channel (PRACH), physical uplink link sharing
Road (PUSCH) and physical uplink control channel (PUCCH) provide.It is PUCCH transmission distribution in uplink band broadside
The specific frequency resources of edge (for example, the multiple of 180 KHz in LTE, this depends on system bandwidth).PUCCH is mainly used by UE
Only wherein not yet to distribute the control information transmitted in uplink in subframe of any RB for PUSCH transmission for UE.Control
Signaling can be by the feedback of the hybrid automatic repeat-request (HARQ) as the response to downlink transmission, channel status reporting
(CSR), the composition such as report, channel quality indicator (CQI) is dispatched.
On the other hand, PUSCH is mainly used for data transmission.But this channel is also used for data correlation control signaling (example
Such as, transformat instruction, multiple-input and multiple-output (MIMO) parameter etc.).This control information to processing uplink data be to
It closes important, and is therefore transmitted together with that data.
The concept of virtual resource blocks (VRB) and Physical Resource Block (PRB) is had been incorporated into LTE.To the real resource of UE
Basic of distribution VRB is to progress., centralized and distributed there are two kinds of resource allocations, i.e.,.It is distributed in centralized resources
In, VRB is to mapping directly to PRB pair, therefore two continuous and centralization VRB is also used as in frequency domain continuous P RB are placed.Separately
On the one hand, virtual reality B is not mapped into the continuous P RB in frequency domain；Therefore the data to be transmitted using these virtual realities B
Channel provides frequency diversity.
Downlink transmission is dynamically dispatched, for example, in each subframe base station transmission with to which terminal transmission data and
The related control information of data is transmitted on which resource block in current downlink subframe.This control signaling is usually each
It is transmitted in preceding 1,2,3 or 4 OFDM symbol in subframe and numerical value n=1,2,3 or 4 is referred to as control format indicator (CFI),
It is indicated by the physics CFI channel (PCFICH) transmitted in the first symbol of control zone.Control zone also includes under physics
Uplink Control Channel (PDCCH), and it is also possible that the ack/nack (ACK/NACK) for carrying uplink transmission
Physical HARQ Indicator Channel (PHICH).
Downlink subframe also includes common reference symbol (CRS), is known to receiver, and for for example controlling
The coherent demodulation of information.Downlink system using CFI=3 OFDM symbol as control is shown in FIG. 3.
Fig. 4 shows example Uplink link transmission subframe.In terms of uplink (UL), detection reference signal (SRS) is
Know signal, transmitted by UE, eNodeB is enabled to estimate different uplink channel property.Detection reference signal has
The duration of single OFDM symbol.These estimations can be used for uplink scheduling and adaptive uplink, but be also used for downlink
Link multiple antenna transmission, especially in the case where uplink and downlink use time division duplex (TDD) of identical frequency.
Detection reference signal is in " the Evolved Universal Terrestrial Radio Access (E- of 3GPP TS 36.211
UTRA);It, is completely integrated to herein by definition in Physical channels and modulation " by quoting
In.Detection reference signal can transmit in the last symbol of 1 ms uplink subframe.The case where for TDD, detection ginseng
Examining signal can also the transmission in special time slot, i.e. uplink pilot time slot (UpPTS).The length of UpPTS can be configured to one
A or two symbols.Fig. 5 shows the 10 ms radio frame of example of TDD, wherein in each of two 5 time slot subframes, downlink chain
The ratio of road (DL) time slot and uplink (UL) time slot is 3DL:2UL, and can reserve a total of eight for detection reference signal
Symbol.The configuration of SRS symbol, such as SRS bandwidth, SRS frequency domain position, SRS frequency-hopping mode and SRS subframe configuration are used as radio
A part of semi-static setting of resources control (RRC) information element, such as " the Evolved Universal of 3GPP TS 36.331
Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol
Specification " is described, is completely incorporated herein in it by quoting.Which illustrate information elements (IE)
SoundingRS-UL-Config is used to specify the uplink SRS configuration of period and aperiodic detection.
Biconnectivity is the feature defined in the UE angle, and wherein UE can simultaneously connect 1 heterogeneous networks points
It receives and transmits.For example, Fig. 6 shows biconnectivity situation, wherein wireless terminal combines macro radio base station node and low-power section
Point (LPN) is participated in.Biconnectivity is the standard in the synthetic operation of the cell enhancing to the LTE in 3GPP Rel-12
Change considered one of feature.
The case where to the work of converging network point in identical or individual frequency, defines biconnectivity.Each nexus of UE polymerization
Can define individual cell or it can not define individual cell.It also predicts, from UE angle, UE can be in the different nets of UE polymerization
Some form of time division multiplexing (TDM) scheme is applied between network point.This is implied to/from in the physical layer of different converging network points
Communication may not be really simultaneously.
Biconnectivity as feature polymerize with carrier wave and coordinating multiple points (CoMP) transmission has many similitudes.One area
Point factor is, biconnectivity considers loose backhaul and sets to the synchronous desired less strict requirement between nexus
Meter, and thus polymerize with carrier wave and CoMP in contrast, wherein the hypothesis close synchronization and low between the nexus connected
Postpone backhaul.
Biconnectivity can use in many ways.Two kinds of way of example being described more fully below are RRC diversity
With decoupling UL/DL.
By RRC diversity, RRC signaling message can be transmitted via anchoring link and booster link and UE.It is assumed that RRC and point
Group data convergence protocol (PDCP) tip node is located in anchor node, and thus signaling message also via anchor point and booster it
Between backhaul link routed as PDCP payload data unit (PDU) is repeated.In the side UE, it is desirable that repeat physical layer
(PHY)/media access control (MAC)/radio link controls (RLC) example, as shown in fig. 7, and independent RACH process with
Obtain the cell-radio network interim identity (CRNTI) of time synchronization and each link.It is double due to improving mobile robustness
One of primary arguments of connectivity, so RRC diversity is that handover-related message, such as UE measurement report and RRC are reconfigured and asked
Seek the special feature of interest of the transmission of (" switching command ").
The useful situation of the second of biconnectivity is decoupling UL/DL.The main beneficial effect of this feature is that it allows
UE is received from the nexus with highest power received with it send out while DL is transmitted to the point with lowest path loss always
UL is sent to transmit.This is when UE is in the heterogeneous network with macrocell and low power nodes (it is in transimission power with larger difference)
It is middle be when being operated it is useful, as shown in Figure 8.The major deployments situation studied is a kind of situation, wherein converging network section
Put the loose backhaul that there are them between network node.
Although in fig. 8 as an example shown in biconnectivity there are some beneficial effects, can be how to having
The UE execution uplink transmission simultaneously of biconnectivity still has to be solved.UE behavior and necessary signaling should all be designated.This
It is related to several aspects, such as node identification and association and UE behavior definition at different conditions, such as PUSCH/ at the same time
HARQ-ACK and period/aperiodic channel status information (CSI) multiplexing in the case where PUCCH transmission while SRS transmission etc..
As an example, therefore the downlink connection to node must be connect with the uplink to same node (for HARQ-ACK
+ CSI) group pair, and vice versa.
